== Plan ==
 
To account for resource usage across multiple resource providers we need to define:
 
 
 
# the elements to be accounted for and how accounting data may be gathered. (This relates to the statement  “Resource providers agree and follow the same rules for accounting the resource usage”.)
 
# how accounting data will be published
 
# what is required from this data (for VM users, Resource Providers, VO Managers, others?)
 
 
 
== Cloud Accounting Draft Usage Record ==
 
The latest draft schema attempts to map the Cloud Accounting Usage Record fields to fields used by Venus-C and OpenNebula. [https://oerc.basecamphq.com/projects/7732005/file/115130463/Current%20Version-CloudAccountingUR.pdf Draft - Cloud Accounting Usage Record]
 
 
 
 
 
==== Compute Accounting Record ====
 
To help define what we will account for the existing [https://twiki.cern.ch/twiki/pub/EMI/ComputeAccounting/CAR-EMI-tech-doc-0.8.doc Compute Accounting Record] could be extended. 
 
 
 
==== Previous versions: ====
 
[https://oerc.basecamphq.com/projects/7732005/file/115129730/CloudAccountingUR-v2.pdf - Version 2 - Cloud Accounting Usage Record]
 
[https://oerc.basecamphq.com/projects/7732005/file/105129409/Draft-CloudAccountingUsageRecord-v1.pdf Version 1 - Cloud Accounting Usage Record]).
 
 
 
== Publishing Accounting Data ==
 
 
 
==== Cloud Accounting System ====
 
The software and technology choices for the new APEL system (which receives compute accounting records) will be used to provide a ‘testbed’ so that the resource providers can send records to a Cloud Accounting System at STFC.  The software is written in Python and the data is stored in a MySQL database, the component parts of the system are:
 
 
 
# SSM
 
# Record loader
 
# MySQL Database
 
 
 
More detail available in the Cloud Accounting System document here:

==== Work on providing OpenNebula Accounting Records ====
 
 
 
Contact made with "VENUS" project developers who have developed a system for extracting accounting data.  Detail on the Cloud Accounting System (above) provided to them, requested more detail on their implementation.
